The U.S. National Oceanic and Atmospheric Administration’s (NOAA) Climate Prediction Center on Thursday issued an El Nino watch for the next six months, a climate pattern that is likely to play a role in this year’s Atlantic hurricane season. 

In a statement, NOAA said the indications are favorable — a 62% chance — for an El Nino pattern to form sometime from May to July. The pattern is characterized by warmer ocean temperatures and higher than normal precipitation in the central to eastern Pacific Ocean. 

The El Nino pattern would follow nearly two continuous years of La Nina conditions in the Pacific. 

El Nino and La Nina are opposite extremes of the El Nino-Southern Oscillation (ENSO) climate pattern that occur across the equatorial Pacific and can influence weather across the United States and around the world. NOAA monitors ENSO and issues monthly outlooks on the patterns. 

The agency’s El Nino watch comes as the first forecast for the 2023 Atlantic hurricane season was issued by Colorado State University (CSU), led by meteorologist Philip Klotzbach. 

The CSU forecast calls for a slightly below normal hurricane season but cautions there is a great deal of uncertainly as the forecast depends heavily on the likelihood of El Nino forming and how strong it might be. The warmer than normal ocean temperatures associated with El Nino are conducive to an active hurricane season. 

The CSU forecast predicts 13 named storms to form during the 2023 season compared with the annual average of 14.4. Of those, CSU predicts six would become hurricanes, compared with the annual average of 7.2. 

The forecasters predict two of those will become major hurricanes — those with winds topping 179 kilometers per hour — compared with the average of three. 

The official Atlantic hurricane season of the U.S. National Weather Service, which is part of NOAA, runs from June 1 to November 30 each year.

Ghana has become the first country to approve a new malaria vaccine described as a “world changer” by scientists who developed it at the University of Oxford.

The mosquito-spread parasitic disease kills more than 600,000 people every year. The majority are children in sub-Saharan Africa.

A statement issued Wednesday by Oxford University says its new malaria vaccine called R21 has secured regulatory approval by Ghanaian officials for use in the age group at highest risk of death from malaria — children age 5-to-36 months.

Malaria is an endemic disease in Ghana. The West African country’s health service says it accounts for 38% of all outpatients, with the most vulnerable groups being children younger than 5 years old.

“We have tested a lot of vaccines — and to be here now, to have a vaccine that is being approved first for use in Ghana — is fantastic. It is what we’ve all been working hard towards,” said Dr. Katie Ewer, head of malaria immunology and professor of vaccine immunology at the Jenner Institute at the University of Oxford.

Ewer said R21 has higher efficacy — about 75% in the data from the phase two trial. “We think perhaps the durability of the response has been better as well,” she said.

Some hesitant to accept vaccine

Ghana was one of three African countries in 2019 to have piloted the first malaria vaccine, known as RTS,S. But public acceptance of the vaccine, according to health officials, was somewhat below target due to hesitancy among parents linked to a fear of the unknown.

Ewer says having more malaria vaccines on the market helps parents make a better choice.

“It’s good news that we’ve now got a second malaria vaccine approved,” said Ewer. “And so, people can trust that these vaccines are safe to use. And I hope that people trust the vaccine and will take it up and see for themselves the effect it has.”

The World Health Organization says a child dies every minute from malaria in Africa, where it is estimated that nine out of 10 malaria deaths occur. It is hoped that the new vaccine will help Ghanaian and African children combat malaria.

Vaccine reduces risk

Dr. Nana Yaw Peprah, the head of the National Malaria Control Program in Ghana, told VOA that the Oxford vaccine is coming at the right time.

“The vaccine has a role in the elimination agenda because it reduces the risk of people having the disease and also its severe form,” said Peprah. “The vaccines are for children. If you allow your child to be given this vaccine, the risk of this child, who is actually in the vulnerable group and the risk of getting malaria, really reduces.”

Nearly half of the world’s population is at risk of malaria. In 2020, an estimated 241 million people in 85 countries contracted malaria. That same year, the WHO says the disease claimed approximately 627,000 lives.

The first image of a black hole captured four years ago revealed a fuzzy, fiery doughnut-shaped object. Now, researchers have used artificial intelligence to give that cosmic beauty shot a touch-up.

The updated picture, published Thursday in the Astrophysical Journal Letters, keeps the original shape, but with a skinnier ring and a sharper resolution.

The image released in 2019 gave a peek at the enormous black hole at the center of the M87 galaxy, 53 million light-years from Earth. A light-year is 5.8 trillion miles. It was made using data gathered by a network of radio telescopes around the world, showing swirling light and gas.

But even with many telescopes working together, gaps remained in the data. In the latest study, scientists relied on the same data and used machine learning to fill in the missing pieces.

The resulting picture looks similar to the original, but with a thinner “doughnut” and a darker center, researchers said.

“For me, it feels like we’re really seeing it for the first time,” said lead author Lia Medeiros, an astrophysicist at the Institute for Advanced Study in New Jersey.

Medeiros said the team plans to use machine learning on other images of celestial objects, including possibly the black hole at the center of our Milky Way galaxy.

ChatGPT could return to Italy soon if its maker, OpenAI, complies with measures to satisfy regulators who had imposed a temporary ban on the artificial intelligence software over privacy worries.

The Italian data protection authority on Wednesday outlined a raft of requirements that OpenAI will have to satisfy by April 30 for the ban on AI chatbot to be lifted.

The watchdog last month ordered the company to temporarily stop processing Italian users’ personal information while it investigated a possible data breach. The authority said it didn’t want to hamper AI’s development but emphasized the importance of following the European Union’s strict data privacy rules.

OpenAI, which had responded by proposing remedies to ease the concerns, did not reply immediately to a request for comment Wednesday.

Concerns about boom grow

Concerns are growing about the artificial intelligence boom, with other countries, from France to Canada, investigating or looking closer at so-called generative AI technology like ChatGPT. The chatbot is “trained” on huge pools of data, including digital books and online writings, and able to generate text that mimics human writing styles.

Under Italy’s measures, OpenAI must post information on its website about how and why it processes the personal information of both users and non-users, as well as provide the option to correct or delete that data.

The company will have to rely on consent or “legitimate interest” to use personal data to train ChatGPT’s algorithms, the watchdog said.

Regulators question legal basis

The Italian regulators had questioned whether there’s a legal basis for OpenAI to collect massive amounts of data used to teach ChatGPT’s algorithms and raised concerns the system could sometimes generate false information about individuals.

San Francisco-based OpenAI also will have to carry out a publicity campaign by May 15 through radio and TV, newspapers and the internet to inform people about how it uses their personal data for training algorithms, Italy’s watchdog said.

There’s also a requirement to verify users’ ages and set up a system to filter out those who are under 13 and teens between 13 and 18 who don’t have parental consent.

“Only in that case will the Italian SA (supervisory authority) lift its order that placed a temporary limitation on the processing of Italian users’ data … so that ChatGPT will be available once again from Italy,” the watchdog said on its website.

Broadcaster National Public Radio said Wednesday it would no longer post its news content on 52 official Twitter accounts in protest of the social media site labeling the independent U.S. news agency as “government-funded media.” 

NPR is the first major news organization to go silent on Twitter. The social media platform owned by entrepreneur Elon Musk at first labeled NPR as “state-affiliated media,” the same tag it applies to propaganda outlets in China, Russia and other autocratic countries. 

Twitter then revised its label to “government-funded media,” but NPR said that, too, was misleading because NPR is a private, nonprofit company with editorial independence. NPR says it receives less than 1% of its $300 million annual budget from the federally funded Corporation for Public Broadcasting.  

NPR chief executive John Lansing said that by not posting its news reports on Twitter, the network is protecting its credibility and would continue to produce journalism without “a shadow of negativity.” 

In an email to staff explaining the decision, Lansing wrote, “It would be a disservice to the serious work you all do here to continue to share it on a platform that is associating the federal charter for public media with an abandoning of editorial independence or standards.”  

He said that even if Twitter were to drop any description of NPR, the network would not immediately return to the platform. 

“At this point I have lost my faith in the decision-making at Twitter,” Lansing said in an article posted by NPR. “I would need some time to understand whether Twitter can be trusted again.”

Twitter has also labeled Voice of America, a U.S. government-funded but independent news agency, and the BBC in Britain, as “government-funded media,” a description more commonly employed in describing state-controlled propaganda outlets. VOA has not dropped its use of Twitter but said its description of the news outlet left the impression that it was not independent. 

Bridget Serchak, VOA’s director of public relations, said, “The label ‘government funded’ is potentially misleading and could be construed as also ‘government-controlled’ — which VOA is most certainly not.” 

“Our editorial firewall, enshrined in the law, prohibits any interference from government officials at any level in its news coverage and editorial decision-making process,” Serchak said in an email. “VOA will continue to emphasize this distinction in our discussions with Twitter, as this new label on our network causes unwarranted and unjustified concern about the accuracy and objectivity of our news coverage.” 

VOA is funded by the U.S. government and is part of the U.S. Agency for Global Media, but its editorial independence is protected by regulations and a firewall. The BBC said it “is, and always has been, independent.” 

Press freedom advocates have also objected to Twitter’s labeling of NPR, VOA and the BBC.

“The confusion between media serving the general interest and propaganda media is dangerous, and is yet further proof that social media platforms are not competent to identify what is and is not journalism,” Vincent Berthier, head of the technology desk at Reporters Without Borders, said in a statement.

A Biden administration proposal would force U.S. automakers to sharply increase their production of electric cars and trucks over the next decade, lending greater urgency to the effort to build raw material supply chains that reduce the industry’s dependence on China.

The Environmental Protection Agency on Wednesday announced a proposed rule that would place stricter limits on the average tailpipe emissions of vehicles built in the United States. The proposal would reduce the allowable limit by so much that automakers would have no way to comply unless about two-thirds of the vehicles they produce by 2032 are emission-free electric vehicles.

Automakers have generally recognized that EVs represent the future of the industry, but Wednesday’s proposal would greatly accelerate the trend. The proposal, which will be open to public comment before it is finalized, would greatly reduce a leading cause of air pollution in the U.S., as well as the greenhouse gases that contribute to global warming.

“By proposing the most ambitious pollution standards ever for cars and trucks, we are delivering on the Biden-Harris administration’s promise to protect people and the planet, securing critical reductions in dangerous air and climate pollution, and ensuring significant economic benefits like lower fuel and maintenance costs for families,” said EPA Administrator Michael Regan.

The proposal, which would apply to new light-duty vehicles made in 2027 and beyond, would be the strictest environmental standard the federal government has ever applied to automobiles. If it does force the industry to make EVs account for two-thirds of production, it could also exceed President Joe Biden’s previously articulated target of making 50% of new cars either plug-in hybrids or completely emission-free by 2030.

Supply chain questions

Well before the EPA released its proposed rule Wednesday, the Biden administration had been moving to strengthen the EV market in the U.S. and to build a pipeline for raw materials that would reduce the auto industry’s reliance on China for key raw materials.

Accomplishing that reduction will be no small task. According to an analysis by the International Energy Agency last year, China produced three-quarters of the world’s lithium-ion batteries, the key component in the majority of EVs on the road.

China also has a dominant hold on much of the market for the components of those batteries, including lithium, cobalt and graphite. According to the IEA, more than half of the world’s capacity for processing and refining those materials is located in China.

According to the IEA, as of last year, the U.S. accounted for only 10% of EV production worldwide, and just 7% of production capacity for batteries.

Infrastructure projects

Last year’s passage of the Inflation Reduction Act, which contained hundreds of billions of dollars in climate-related spending, included the creation of large tax breaks restricted to EVs made at least partly in the U.S. The tax breaks are meant to extend over several years, but the restrictions become tighter as time goes on, creating incentives for manufacturers to “onshore” production to the U.S.

Tax breaks specific to the batteries used in EVs require that the raw materials used to assemble them come from domestic sources or from countries with which the U.S. has existing trade agreements.

Other pieces of legislation meant to spur investment in the U.S., including a major bipartisan infrastructure bill and the CHIPS and Science Act, also contain money and incentives that will help build out electric infrastructure in the U.S.

Achievable goals

Luke Tonachel, senior director for clean vehicles and buildings with the Natural Resources Defense Council, told VOA that building an EV supply chain centered on domestic production and imports from friendly countries is ambitious, but achievable.

Tonachel said the necessary raw materials are available from U.S. allies, but that the capacity for processing them needs to be built domestically. He said the creation of that capacity is already underway.

“There are robust incentives for building out that battery manufacturing and supply chain here in the U.S.,” he said, adding that he believes the administration’s time frame is feasible, especially now that the new standards have created certainty about future demand for EVs.

“It is realistic,” he said. “These are technologies that are known. We can certainly get more economies of scale as we ramp up production.”

Automakers tentative

Industry representatives said achieving the administration’s goal will require that a lot of disparate efforts be successful at the same time, not all of which are under their control. For example, a nationwide network of charging stations and the increased capacity to meet new demand for power will be essential to driving customer demand.

“It’s aggressive, and a lot of pieces have to work perfectly together,” Genevieve Cullen, president of the Electric Drive Transportation Association, told VOA. “Aside from the technology piece, the market piece has to work, and supply chain speed is part of that. Consumer incentives are working to help bring them into the equation, and we need to keep expanding infrastructure at a pace that meets, and perhaps exceeds, the needs in the beginning so that people feel the confidence that they need to switch to battery electric.”

John Bozzella, president of the trade group Alliance for Automotive Innovation, said in a blog post Wednesday that the administration’s plan is “aggressive by any measure” and that its success would depend on more than just automakers being able to ramp up production.

“To some extent, the baseline policy framework for the transition has come into focus,” Bozzella said. “But it remains to be seen whether the refueling infrastructure incentives and supply-side provisions of the Inflation Reduction Act, the bipartisan infrastructure law, and the CHIPS and Science Act are sufficient to support electrification at the levels envisioned by the proposed standards over the coming years.”

A plan to legalize irrigation around the Donana wildlife reserve in southern Spain, one of Europe’s largest wetlands and a wintering location for migratory birds, has sparked an outcry during a prolonged drought.

Andalusia’s conservative regional government wants to allow agricultural irrigation in five municipalities around Donana, saying the move poses no risk to the national park.

The regional assembly, where the conservatives have a majority, on Wednesday voted in favor of proceeding with detailed studies of the proposal.

During the debate, a lawmaker for the left-wing Adelante Andalucia party emptied a glass full of sand on regional leader Juanma Moreno’s vacant seat after accusing him of wanting to “dry up” Donana.

‘No water at all’

Scientists and the national government warn the park is in critical condition with lagoons drying out and biodiversity disappearing, and want a reduction in water extracted.

“There is no water at all. It makes no sense to promise something that is not there,” Environment Minister Teresa Ribera said on Tuesday, vowing to take all possible legal measures to protect Donana from the move “that directly attacks one of the country’s most precious ecosystems.”

While some irrigation is already allowed, many farmers use illegal wells that drain underwater reserves. The central government closed this week 220 illegal wells and plans to close hundreds more in the near future.

The European Commision, which has already taken Spain to court for failure to protect the wetlands, warned last month the plan could lead to sanctions.

Home to eagles, lynx, more

Donana boasts lagoons, marshlands, scrub woodland, beaches and sand dunes and is home to fallow deer, badgers and endangered species including the Spanish imperial eagle and the Iberian lynx.

Spain is in the grip of a long-term drought after 36 months of poor rainfall. The Guadalquivir basin, where Donana is located, and Catalonia in the northeast are two of the most affected areas.

Exacerbating the drought, scientists say, is illegal use of underground waters by local red fruit producers in greenhouses and by tourism ventures that have mushroomed around Donana.

A study by the Spanish National Research Council said this week 19% of Donana’s 267 lagoons have disappeared over the past decade, and the number of wintering migratory birds dropped to below 90,000 from some 500,000.

Campaign group Greenpeace said in a statement the proposed regulation “threatens the survival of Donana, one of Europe’s most emblematic natural areas, and punishes (legal) irrigators who have been complying with the law.”

Hospitals in Cameroon are reporting an increase in cases of river blindness, a parasitic disease caused by bites from infected blackflies. Hundreds of aid workers have been dispatched to remote, riverside villages to encourage those infected to seek treatment. 

In Sa’a district, 74 kilometers north of Cameroon’s capital of Yaounde, 45-year-old Jean Christophe Onana says he has not been able to recover his sight after receiving treatment from an African traditional healer for two months. He says he strongly believes that he has been bewitched by his enemies who are envious of last year’s abundant yield from his cocoa farm.

Aid workers say Onana suffers from river blindness, a parasitic disease particularly prevalent in Africa, where 99% of all cases occur.

Cameroon’s ministry of public health says that hospitals in Lekie, the administrative unit where Sa’a is located, have reported several hundred fresh cases of river blindness within the past three months. 

The central African state’s government says the increase is in areas where there have been floods and where new farmland was opened near rivers, attracting settlers.

Ophthalmologist Raoul Edgard Cheuteu, one of the aid workers in Sa’a, says humanitarian agencies and the government of Cameroon have decided to jointly equip the Sa’a district hospital and scores of other hospitals in areas where there is an increase in river blindness cases with standard tests for the diagnosis of the disease. Cheuteu says Onchocerciasis is increasing in Sa’a because of its many rivers that are breeding sites for blackflies that transmit river blindness.

Aid workers are educating civilians in Cameroon riverside villages that river blindness is not a spell or divine punishment for wrongdoing but an infection that can be controlled and treated at hospitals.

Cameroon reports that youths are deserting remote villages where the number of people suffering from the parasitic disease of the skin and eyes transmitted by the blackfly is increasing. 

The Cameroon government says besides Sa’a, several hundred hospitals in Cameroon’s Centre, East and South regions have reported at least 6,000 new infections within three months.

The figures may be higher since 70% of Cameroonians go for African traditional medicine where it is difficult to collect data, the government says.

The Global Institute for Disease Elimination, GLIDE, works with the Cameroon ministry of Public Health to help accelerate treatment for river blindness, a neglected tropical disease.

GLIDE’s top official, Dr. Aissatou Diawara, says river blindness is a public health concern in Cameroon because about 6 million of the country’s 26 million inhabitants are already infected.

“Despite two decades of annual treatment or community-directed treatment with ivermectin or CDTI, confirmed cases of Onchocerciasis are still present in 113 health districts previously classified as hyperendemic,” Diawara said via a messaging app. “So the use of test and treat strategy and addressing communities to get used to treatment are essential steps towards eliminating Onchocerciasis in Cameroon.”

Diawara says blackflies that transmit river blindness breed along fast-flowing rivers and streams, close to remote villages located near fertile land where people rely on agriculture. She said river blindness is transmitted to humans through exposure to repeated bites of infected blackflies and symptoms include severe itching, disfiguring skin conditions and visual impairment, including permanent blindness.

The United Nations says Onchocerciasis occurs mainly in tropical areas, with more than 99% of infected people living in 31 countries in sub-Saharan Africa.

Electronic cigarette-maker Juul Labs will pay $462 million to six states and the District of Columbia, marking the largest settlement the company has reached so far for its role in the youth vaping surge, New York Attorney General Letitia James said Wednesday.

The agreement with New York, California, Colorado, Illinois, Massachusetts, New Mexico and Washington, D.C., marks the latest in a string of recent legal settlements Juul has reached across the country with cities and states.

The vaping company, which has laid off hundreds of employees, will pay $7.9 million to settle a lawsuit alleging the company violated West Virginia’s Consumer Credit and Protection Act by marketing its products to underage users, the state’s Attorney General Patrick Morrisey announced Monday. Last month, the company paid Chicago $23.8 million to settle a lawsuit.

Minnesota’s case against Juul went to trial last month with the state’s Attorney General Keith Ellison asserting that the company “baited, deceived and addicted a whole new generation of kids after Minnesotans slashed youth smoking rates down to the lowest level in a generation.”

Like some other settlements reached by Juul, this latest agreement includes various restrictions on the marketing, sale and distribution of the company’s vaping products. For example, it is barred from any direct or indirect marketing that targets young people, which includes anyone younger than 35. Juul is also required to limit the purchases customers can make in retail stores and online.

“Juul lit a nationwide public health crisis by putting addictive products in the hands of minors and convincing them that it’s harmless,” James said in a statement. “Today they are paying the price for the harm they caused.”

James said the $112.7 million due to New York will pay for underage smoking abatement programs across the state.

District of Columbia Attorney General Brian Schwalb said in a statement that Juul “knew how addictive and dangerous its products were and actively tried to cover up that medical truth.”

A spokesperson for the Washington, D.C.-based Juul said that with Wednesday’s settlement, “we are nearing total resolution of the company’s historical legal challenges and securing certainty for our future.”

The spokesperson added that underage use of Juul products has declined by 95% since 2019 based on the National Youth Tobacco Survey. According to the CDC, since surveys were administered online instead of on school campuses during the pandemic, the results cannot be compared to prior years.

In September, Juul agreed to pay nearly $440 million over a period of six to 10 years to settle a two-year investigation by 33 states into the marketing of its high-nicotine vaping products to young people. That settlement amounted to about 25% of Juul’s U.S. sales of $1.9 billion in 2021.

Three months later, the company said it had secured an equity investment to settle thousands of lawsuits over its e-cigarettes brought by individuals and families of Juul users, school districts, city governments and Native American tribes.

Juul rocketed to the top of the U.S. vaping market about five years ago with the popularity of flavors like mango and mint. But the startup’s rise was fueled by use among teenagers, some of whom became hooked on Juul’s high-nicotine pods.

Parents, school administrators and politicians have largely blamed the company for a surge in underage vaping.

The U.S. Environmental Protection Agency (EPA) on Wednesday proposed sweeping emissions cuts for new cars and trucks through 2032, a move it says could mean two out of every three new vehicles automakers sell will be electric within a decade.

The proposal, if finalized, represents the most aggressive U.S. vehicle emissions reduction plan to date, requiring 13% annual average pollution cuts and a 56% reduction in projected fleet average emissions over 2026 requirements. The EPA is also proposing new stricter emissions standards for medium-duty and heavy-duty trucks through 2032.

The EPA projects the 2027-2032 model year rules would cut more than 9 billion tons of CO2 emissions through 2055 – equivalent to more than twice total U.S. CO2 emissions last year.

Automakers and environmentalists say the administration is moving quickly in order to finalize new rules by early 2024 to make it much harder for a future Congress or president to reverse them. Then President Donald Trump rolled back tough emissions limits through 2025 set under Barack Obama but the Biden administration reversed the rollback.

The agency estimates net benefits through 2055 from the proposal range from $850 billion to $1.6 trillion. By 2032 the proposal would cost about $1,200 per vehicle per manufacturer, but save an owner more than $9,000 on average on fuel, maintenance, and repair costs over an eight-year period.  

“A lot has to go right for this massive – and unprecedented – change in our automotive market and industrial base to succeed,” said John Bozzella, CEO of the Alliance for Automotive Innovation representing General Motors GM.N, Volkswagen VOWG_p.DE, Toyota 7203.T and others.

“Factors outside the vehicle, like charging infrastructure, supply chains, grid resiliency, the availability of low carbon fuels and critical minerals will determine whether EPA standards at these levels are achievable.”

The proposal is more ambitious than President Joe Biden’s 2021 goal, backed by automakers, seeking 50% of new vehicles by 2030 to be electric vehicles (EVs) or plug-in hybrids. Stellantis STLAM.MI said it was “surprised that none of the alternatives align with the President’s previously announced target of 50% EVs by 2030.”

The Biden administration is not proposing banning gasoline-powered vehicles, but wants comments on whether it should extend emissions rules through 2035 and on other alternatives. Some environmental groups want the EPA to set tougher rules, especially on heavy trucks.

“These standards are very ambitious and they track with the sense of urgency that the president and this administration have as we tackle the climate crisis,” EPA Administrator Michael Regan said in a Reuters interview, declining to endorse setting a date to end the sale of new gasoline-powered vehicles. He emphasized the proposal is a “performance-based standard” and not an EV mandate.

Under the EPA proposal, automakers are forecast to produce 60% EVs by 2030 and 67% by 2032 to meet requirements – compared with just 5.8% of U.S. vehicles sold in 2022 that were EVs. The National Highway Traffic Safety Administration plans to propose parallel economy standards in the coming weeks.

California in August moved to require all new vehicles sold in the state by 2035 be electric or plug-in electric hybrids, but must still seek an EPA waiver to proceed. Regan would not to say how the EPA would react to a California request. “We’ll be on the lookout for that if it were to ever come,” he said.

Dan Becker, director of the Safe Climate Transport Campaign, said the EPA proposal should have been tougher.

“Automakers talk out of both sides of their tailpipes, promising electric vehicles while delivering mostly the same old gas-guzzlers and lobbying for weak, loophole-riddled rules,” Becker said.

Under the proposal, the EPA estimates 50% of new vocational vehicles like buses and garbage trucks could be EVs by 2032, along with 35% of new short-haul freight tractors and 25% of new long-haul freight tractors. Medium-duty vehicle rules are projected to cut emissions by 44% over 2026.

Billionaire Elon Musk has told the BBC that running Twitter has been “quite painful” but that the social media company is now roughly breaking even after he acquired it late last year.

In an interview also streamed live late Tuesday on Twitter Spaces, Musk discussed his ownership of the online platform, including layoffs, misinformation and his work style.

“It’s not been boring. It’s quite a rollercoaster,” he told the U.K. broadcaster at Twitter’s San Francisco headquarters.

It was a rare chance for a mainstream news outlet to interview Musk, who also owns Tesla and SpaceX. After buying Twitter for $44 billion last year, Musk’s changes included eliminating the company’s communications department.

Reporters who email the company to seek comment now receive an auto-reply with a poop emoji.

The interview was sometimes tense, with Musk challenging the reporter to back up assertions about rising levels of hate speech on the platform. At other times, Musk laughed at his own jokes, mentioning more than once that he wasn’t the CEO but his dog Floki was.

He also revealed that he sometimes sleeps on a couch at Twitter’s San Francisco office.

Advertisers who had shunned the platform in the wake of Musk’s tumultuous acquisition have mostly returned, the billionaire said, without providing details.

Musk predicted that Twitter could become “cash flow positive” in the current quarter “if current trends continue.” Because Twitter is a private company, information about its finances can’t be verified.

After acquiring the platform, Musk carried out mass layoffs as part of cost-cutting efforts. He said Twitter’s workforce has been slashed to about 1,500 employees from about 8,000 previously, describing it as something that had to be done.

“It’s not fun at all,” Musk said. “The company’s going to go bankrupt if we don’t cut costs immediately. This is not a caring-uncaring situation. It’s like if the whole ship sinks, then nobody’s got a job.”

Asked if he regretted buying the company, he said it was something that “needed to be done.”

“The pain level of Twitter has been extremely high. This hasn’t been some sort of party,” Musk said.

The U.S. has named a veterinary tranquilizer as an “emerging threat” when it’s mixed with the powerful opioid fentanyl, clearing the way for more efforts to stop the spread of xylazine.

The Office of National Drug Control Policy announced the designation Wednesday, the first time the office has used it since the category for fast-growing drug dangers was created in 2019.

Dr. Rahul Gupta, director of the drug policy office, said xylazine has become increasingly common in all regions of the country.

It was detected in about 800 drug deaths in the U.S. in 2020 — most of them in the Northeast. By 2021, it was present in more than 3,000 fatalities —with the most in the South — according to a report last year from the Drug Enforcement Administration.

“We cannot ignore what we’re seeing,” Gupta said. “We must act and act now.”

Xylazine was approved for veterinary use in 1971. Sometimes known as “tranq,” it’s been showing up in supplies of illicit drugs used by humans in major quantities in only the last several years.

It’s believed to be added to other drugs to increase profits. Officials are trying to understand how much of it is diverted from veterinary uses and how much is made illicitly.

The drug causes breathing and heart rates to slow down, sometimes to deadly levels, and causes skin abscesses and ulcers that can require amputation. Withdrawal is also painful.

While it’s often used in conjunction with opioids, including fentanyl and related illicit lab-made drugs, it’s not an opioid. And there are no known antidotes.

Gupta said his office is requesting $11 million as part of its budget to develop a strategy to tackle the drug’s spread. Plans include developing an antidote, learning more about how it is introduced into illicit drug supplies so that can be disrupted, and looking into whether Congress should classify it as a controlled substance.

Gupta said it needs to be available for veterinary uses even amid crackdowns on the supply used by people. He also said systems to detect the drug and data about where it’s being used need to be improved.

The drug is part of a deepening overdose crisis in the U.S.

The U.S. Centers for Disease Control and Prevention estimates that more than 107,000 people died from overdoses in the 12 months that ended Oct. 31, 2022. Before 2020, the number of overdose deaths had never topped 100,000.

Most of the deaths were linked to fentanyl and other synthetic opioids. Like xylazine, they’re often added to other drugs — and users don’t always know they’re getting them.

U.S. health officials released data Tuesday showing how chlamydia, gonorrhea and syphilis cases have been accelerating, but doctors are hoping an old drug will help fight the sexually transmitted infections.

Experts believe STDs have been rising because of declining condom use, inadequate sex education, and reduced testing during the COVID-19 pandemic.

Millions of Americans are infected each year. Rates are highest in men who have sex with men, and among Black and Hispanic Americans and Native Americans.

“Sexually transmitted infections are an enormous, low-priority public health problem. And they’ve been a low-priority problem for decades, in spite of the fact that they are the most commonly reported kind of infectious disease,” said Dr. John M. Douglas Jr., a retired health official who lectures at the Colorado School of Public Health.

To try to turn the tide, many doctors see promise in doxycycline, a cheap antibiotic that has been sold for more than 50 years.

The Centers for Disease Control and Prevention is drafting recommendations for using it as a kind of morning-after pill for preventing STDs, said Dr. Leandro Mena, director of the agency’s STD prevention division.

The drug is already used to treat a range of infections. A study published last week in The New England Journal of Medicine showed its potential to prevent sexually transmitted infections.

In the study, about 500 gay men, bisexual men and transgender women in Seattle and San Francisco with previous STD infections took one doxycycline pill within 72 hours of unprotected sex. Those who took the pills were about 90% less likely to get chlamydia, about 80% less likely to get syphilis, and more than 50% less likely to get gonorrhea compared with people who did not take the pills after sex, the researchers found.

The study was led by researchers at the University of California, San Francisco and built on a similar French study that saw promise in the idea.

“We do need new approaches, new innovations” to help bring sexually transmitted infections under control, said Dr. Philip Andrew Chan, who is consulting with the CDC on the doxycycline recommendations.

Mena, of the CDC, said there is no sign the STD trend is slowing.

Mississippi had the highest rate of gonorrhea cases, according to 2021 CDC data released Tuesday. Alaska saw a sharp increase in its chlamydia case rate that allowed it to overtake Mississippi at the top of that list. South Dakota had the highest rate of early-stage syphilis.

Arizona had the highest rate of cases in which infected mothers pass syphilis on to their babies, potentially leading to death of the child or health problems like deafness and blindness.

Using an antibiotic to prevent these kinds of infections won’t “be a magic bullet. but it will be another tool,” said Chan, who teaches at Brown University and is chief medical officer at Open Door Health, a health center for gay, lesbian and transgender patients in Providence, Rhode Island.

Experts noted the CDC will have many factors to weigh as it develops the recommendations.

Among them: The drug can cause side effects such as stomach problems and rashes after sun exposure. Some research has found it ineffective in heterosexual women. And widespread use of doxycycline as a preventive measure could contribute to mutations that make bacteria impervious to the drug, as has happened with antibiotics before.

Nevertheless, the San Francisco Department of Public Health in October became the first U.S. health department to issue guidance about doxycycline as an infection-prevention measure. And some other clinics have been recommending the antibiotic to patients who may be at higher risk.

Derrick Woods-Morrow, a 33-year-old artist and an assistant professor at the Rhode Island School of Design, is an early adopter. Woods-Morrow said he isn’t a fan of condoms — they can break, and sometimes people slip them off during sex. But he wants to stay healthy.

About a decade ago, he started taking an anti-viral medication before sex to protect himself from HIV infection. Five years ago, a doctor told him about research into whether doxycycline might protect people from other diseases.

“I thought it was probably in my best interest to protect myself and my partners, as well,” he said. He said it’s been a positive experience, and that he hasn’t tested positive for chlamydia, gonorrhea or syphilis while using it.

“I feel like it’s a tool to sort of take back the sexual freedoms that someone may have lost and to really enjoy sex and interactions with people with a peace of mind,” he said.

Even before he has dipped his toes into the murky waters of Paris ‘ famous but forbidden River Seine, French triathlete Thibaut Rigaudeau is already fielding questions from disbelieving friends.

“Are you scared of swimming in the Seine?” he says they ask him. “It looks disgusting.'”

For decades, it was. Though immortalized in art, literature and song, and cherished by lovers who whisper sweet nothings or tearfully part on the privacy of its banks, the river was ecologically dying. It was too toxic for most fish and for swimmers, largely useful only as a waterway for goods and people or as a watery grave for discarded bicycles and other trash. Swimming in the Seine has, with some exceptions, been off-limits since 1923.

Now, however, its admittedly unappetizing green-brown waters hide a tale of rebirth.

A costly and complex cleanup is resuscitating the Seine just in time for it to play a starring role in the 2024 Paris Olympics and, after that, for it to genuinely live up to its billing as the world’s most romantic river, one that’s actually fit again for people. And in a warming world, a renewed ability to take cooling dips in the river should help France’s capital remain livable during increasingly frequent heat waves. It possibly might also inspire other cities to invest in reclaiming their waterways.

“It will create waves, so to speak, across the world because a lot of cities are watching Paris,” says Dan Angelescu, a scientist who is tracking the Seine’s water quality for City Hall, with regular sampling.

“It’s the beginning of a movement,” he says. “We hope so, at least.”

The Olympic deadline has supercharged a cleanup that has been decades in the making. Without the imperative of having to be ready for 10,500 Olympians in July and August next year, followed by 4,400 Paralympians, City Hall officials say it would have taken many more years to fund the multi-pronged, 1.4 billion-euro ($1.5 billion) effort. Because as well as hosting outdoor swim races, the Seine is going to be the centerpiece of Paris’ unprecedented Olympic opening ceremony. For the first time, it will take place not in a stadium setting but along the river and its banks.

So it needs to be ready. Officials have been going after homes upstream of Paris and houseboats on the Seine that were emptying their sewage and wastewater directly into the river. An Olympic law adopted in 2018 gave moored boats two years to hook up to Paris’ sewage network. Sewage treatment plants on the Seine and its tributary, the Marne, are also being improved.

And more than half a billion euros (dollars) is going into huge storage basins and other public works that will reduce the need to spill bacteria-laden wastewater into the Seine untreated when it rains. One storage facility is being dug next to Paris’ Austerlitz train station. The giant hole will hold the equivalent of 20 Olympic swimming pools of dirty water that will now be treated rather than being spat raw through storm drains in the river.

City Hall says the water quality is already improving and that there are many more types of fish than the two or three species that were the only ones hardy enough to survive in the filth a few decades ago. It says samples taken daily last July and August in the stretch of river where Olympians and Paralympians will compete showed the water quality was overwhelmingly “good.” By their sports’ standards, that means acceptable.

Setting off from the Seine’s ornate Alexandre III bridge, triathletes will race first in 2024, with men on July 30, followed by women the next day. Then come marathon swimmers, on Aug. 8 and 9, and para-triathletes on Sept. 1 and 2.

Rigaudeau, who competed in para-triathlon at the 2021 Tokyo games, is thrilled by the prospect. He’s hoping for an early taste of the experience when Paris hosts warm-up swims in the Seine this summer to hone its readiness for 2024. It will be Rigaudeau’s first-ever dip in his home river.

“We will be the ‘testers,'” he says. “I hope we don’t get sick.”

After the games, the river should then reopen to everyone — in the summer of 2025. City Hall says five potential bathing spots are being studied within Paris itself, with others a bit further afield.

Officials hope that after so many years where swimming in the Seine was unthinkable, Parisians will start to feel that it’s safe to go back in the water when they see Olympians and Paralympians leading the way.

“It’s going to change our lives,” Rigaudeau says. “But it’s also true that because everyone thinks that it’s really very dirty, I’m not sure if people will go of their own accord, at least at first.”

China’s internet regulator has unveiled a proposed law that will require makers of new artificial intelligence, or AI, products to submit to security assessments before public release.

The draft law released Tuesday by the Cyberspace Administration of China says that content generated by future AI products must reflect the country’s “core socialist values” and not encourage subversion of state power.  

The draft law also said AI content must not promote discrimination based on ethnicity, race and gender, and should not provide false information.  

The proposed law is expected to take effect sometime this year. The regulations come as several China-based tech companies, including Alibaba, JD.com and Baidu have released a flurry of new so-called generative AI products which can mimic human speech and generate content such as images and texts. The innovative feature has surged in popularity since San Francisco-based OpenAI introduced ChatGPT last November.
